a sheet of acrylic has a mass of 95.2g. Acrylic has a density of 1.19g/cm³ What is the volume of the sheet of acrylic
Answer:
80 cm³
Step-by-step explanation:
Density = mass/volume
1.19 = 95.2/volume
Volume = 95.2/1.19
= 80
Answer:
80 cm cubed
Step-by-step explanation:
The density of a substance is denoted by d = m/V, where d is the density, m is the mass, and V is the volume.
Here, we know that the mass m = 95.2 grams and the density d = 1.19 g/cm cubed. So, plug these values into the formula:
1.19 = 95.2/V
Divide both sides by 1.19 and multiply both sides by V:
V = 95.2/1.19 = 80 cm cubed
Thus, the volume is 80 cm cubed.

A young sumo wrestler decided to go on a special high-protein diet to gain weight rapidly. He started at 90 kilograms and gained weight at a constant rate of 8 lbs. a week.
a. Write a function to represent this situation. Use x and y as your variables.
b. What would his weight be after 8 weeks?
a) The function that represent this situation is y = 90 + 8x.
b) His weight be after 8 weeks is 154 lbs.
Step-by-step explanation:
It is given that,
He started at 90 kilograms.And gained weight at a constant rate of 8 lbs a week.a) Write a function to represent this situation. Use x and y as your variables.
Let 'x' be the number of weeks he gained weight.Let 'y' be the total weight.Hence the equation can be framed as,
Total weight = starting weight + weight gained in x weeks.
We know that, each week he gains 8 lbs. Therefore, for 8 weeks he gained 8x lbs of weight.
⇒ y = 90 + 8x.
∴ The function that represent this situation is y = 90 + 8x.
b) What would his weight be after 8 weeks?
To find his week after 8 weeks, substitute x=8 in the function y = 90 + 8x.
⇒ 90 + 8(8)
⇒ 90 + 64
⇒ 154 lbs.
∴ His weight be after 8 weeks is 154 lbs.

Determine perimeter
Answer:
20cm
Step-by-step explanation:
7.2 + 7.2 + 2.8 + 2.8 = 20
Each side of the rectangle is equal to the side opposite from it. That means you have 2 sides of 7.2 cm and 2 sides of 2.8 cm.
To find perimeter, you add all the sides. So that's 7.2 + 7.2 + 2.8 + 2.8, which is 20 cm altogether.

Step-by-step explanation:
got it right on ed
The required volume of composite figure is 3465 cubic units. Option d is correct.
For composite figure made of triangular pyramid over triangular prism both as congruent base with dimension h = 10 and base =22.
Hight for both pyramid and prism is 19.5 and 25
Volume of composite figure is to be determine,
When two or more solid put together to form new solid is said to be composite figure.
Here,
Volume of a pyramid = 1/3(1/2 base x height of triangle base)*h of
Volume of a pyramid = 1/3*22*10/2*19.5 = 715 cubic units
Similarly, for triangular prism
Volume of a triangular prism= 22*10/2x 25 = 2750 cubic units
Total volume = volume of a triangular (pyramid + prism)
Total volume = 715+2750
Total volume = 3465 cubic units.

On a map the scale is shown as 0.5 inches equaling 15 miles. If two towns
are 2.25 inches apart on the map, what is the distance in miles between
the towns?
Answer:
The distance in miles between the towns is 67.5.
Step-by-step explanation:
Given:
On a map the scale is shown as 0.5 inches equaling 15 miles.
If the distance are 2.25 inches apart on the map between the towns .
Now, to find the distance in miles between the towns.
The distance on the map between the towns = 2.25 inches.
Let the actual distance between the two towns be [tex]x.[/tex]
The scale of the map is 0.5 inches equaling 15 miles.
If, 0.5 is equivalent to 15 miles.
Thus, 2.25 is equivalent to [tex]x.[/tex]
Now, to solve using by cross multiplication method:
[tex]\frac{0.5}{15} =\frac{2.25}{x}[/tex]
By cross multiplying we get:
[tex]0.5x=33.75[/tex]
Dividing both sides by 0.5 we get:
[tex]x=67.5\ miles.[/tex]
The actual distance between the two towns = 67.5 miles.
Therefore, the distance in miles between the towns is 67.5.
How do I solve this equation
Answer: 14
Step-by-step explanation:
the question is just asking you to replace the x and y with the corresponding numbers.
x = 4
y = -3
Since x is 4 squared it would be 16.
-4 times -3 equals positive 12.
That would make the equation
(16 + 12) divided by 2
16 + 12 = 28 divide that by 2 and you’ll get 14.
Answer: 14
Step-by-step explanation:
First plug 4 in for x.
4^2 is equal to 16 because 4 x 4 is 16.
Next, plug in -3 for y.
-4 x -3
4 times 3 is 12 and they are both negative, therefore it turns out as a positive 12.
Then add the numbers on the top of your equation.
16+12=28.
Finally divide the sum by 2.
28 divided by 2= 14
Your answer is 14.

A round mirror has a radius of 5.3 inches. What is the area of the mirror in square inches, rounded to the nearest tenth?
Answer:
88.2 squared
Step-by-step explanation:
The formula to find the area of a circle is a = pi * r ^2
Let's replace the values that we know.
a = 3.14 x 5.3 ^2
First, we should do 5.3 ^2, which is 28.09.
a = 3.14 x 28.09
Now we are able to do 3.14 x 28.09 which is 88.2026
But that isn't it! We need to round to the nearest tenth, which is this digit:
88.2026
Since next to the 2 there is a 0, you take out all the numbers after that 2. Which leaves you with:
88.2
Final answer:
The area of the round mirror with a radius of 5.3 inches, when calculated using the formula A = πr^2 and rounded to the nearest tenth, is 88.2 square inches.
Explanation:To find the area of the round mirror with a radius of 5.3 inches, we will use the formula for the area of a circle, which is A = πr^2, where A is the area, π is approximately 3.14, and r is the radius of the circle.
Given that the radius of the mirror is 5.3 inches, we can substitute this value into the formula to find the area:
A = π(5.3)^2 ≈ 88.2 square inches.
Let's plug in the radius:
A = π * (5.3 inches)^2A = 88.2026 square inchesWhen rounded to the nearest tenth, the area of the mirror is 88.2 square inches.
A person read that the average number of hours an adult sleeps on Friday night to Saturday morning was 7.2 hours. The
researcher feels that college students do not sleep 7.2 hours on average. The researcher randomly selected 15 students and
found that on average they slept 8.3 hours. The standard deviation of the sample is 1.2 hours. If you wanted to test this claim,
what type of statistical test would you do and why?
Calculate the value of z and its probability, since with this we can know how likely it is that this will happen.
We have that the mean (m) is equal to 8.3, the standard deviation (sd) 1.2 and the sample size (n) = 15
They ask us for P (x =7.2)
For this, the first thing is to calculate z, which is given by the following equation:
z = (x - m) / (sd / (n ^ 1/2))
We have all these values, replacing we have:
z = (7.2 - 8.3) / (1.2 / (15 ^ (1/2))
z = -3.55
With the normal distribution table (attached), we have that at that value the approximate probability is:
P (z = -3.55) = 0.0001
The probability is 0.01 %
This affirms that the students do not sleep what the study says because the probability of this happening according to the survey is almost nil.

A cereal company is putting 1 of 4 prizes in each box of cereal. The prizes are evenly distributed so the probability of winning any given prize is always 1 / 4. Lily wonders how many boxes she should expect to buy to get all 4 prizes. She carried out 20 trials of a simulation and her results are shown below. Each dot represents how many boxes it took to get all 4 prizes in that trial.
Answer: The answer is 0.3
Step-by-step explanation:
Lily should expect to buy 1.5 boxes to get all four prizes.
Explanation:This question belongs to the field of probability in Mathematics. The problem is asking how many boxes Lily should expect to buy in order to get all four prizes. This is a geometric problem because each box has a probability of 1/4 of containing a prize, and each trial is independent with the same probability of success. To solve this problem, we can use the concept of expected value.
The expected value is the average number of boxes Lily needs to buy to get all four prizes. The expected value can be calculated by multiplying the probability of each outcome by the number of boxes it takes to achieve that outcome, and then summing up these products:
Expected value = (1/4) * 1 + (1/4) * 2 + (1/4) * 3 + (1/4) * 4 = 1.5
Therefore, Lily should expect to buy approximately 1.5 boxes to get all four prizes.
